Detailed Description
The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The present embodiment provides a drawer type switch cabinet, referring to fig. 1 and 2, which includes a cabinet body 100 and a plurality of drawers 200 that are provided on the cabinet body 100 in a push-pull manner; damping units 300 corresponding to the drawers 200 one by one are arranged on the cabinet body 100, and the damping units 300 apply damping force to the drawers 200 at the tail sections of the pushing paths of the drawers 200 into the cabinet body 100; and a transmission unit 400 is arranged between the drawer 200 and the damping unit 300, and the transmission unit 400 is used for transmitting, so that the drawer 200 can be pulled to the outside of the cabinet 100 to drive the damping unit 300 to be separated from the position where the damping force is applied to the drawer 200. Wherein the cabinet 100 shown in fig. 2 is a portion of the cabinet 100 that mates with the drawer 200.
In summary, in the drawer type switch cabinet of the present embodiment, in the front-stage travel of pushing the drawer 200 into the cabinet body 100, the damping unit 300 does not apply a damping force to the drawer 200, and does not affect the pushing of the drawer 200 into the cabinet body 100; in the end stroke of pushing the drawer 200 into the cabinet 100, the damping unit 300 applies damping force to the drawer 200, so as to avoid excessive speed of the drawer 200 at the end and avoid damage of precise parts in the drawer 200 due to vibration caused by violent collision between the drawer 200 and the cabinet 100.
Moreover, in the drawer type switch cabinet of the present embodiment, by providing the transmission unit 400 between the drawer 200 and the damping unit 300, the pulling of the drawer 200 to the outside of the cabinet body 100 can drive the damping unit 300 to be separated from the position where the damping force is applied to the drawer 200; so that the damping unit 300 applies a damping force to the drawer 200 only at an initial stage when the drawer 200 is pulled outwardly, and the damping unit 300 stops applying the damping force to the drawer 200 after pulling the drawer 200 outwardly for a small distance, so that the drawer 200 is not laborious to pull outwardly.
In a specific structure, referring to fig. 2, the damping unit 300 of the present embodiment includes two damping members 310, where the two damping members 310 are disposed on two sides of the drawer 200 and slidably disposed on the cabinet 100, respectively, and the sliding directions of the two damping members 310 are perpendicular to the push-pull direction of the drawer 200.
Based on the above structure, when the two damping members 310 are slid into contact with the drawer 200, a damping force will be applied to the drawer 200; and when the two damping members 310 slide in a direction away from the drawer 200, the application of damping force to the drawer 200 is stopped.
Referring to fig. 2, the transmission unit 400 of the present embodiment includes a rotatable shaft 410 provided on the cabinet 100, and the shaft 410 can respectively drive the damping member 310 to slide to a position applying a damping force to the drawer 200 and slide to a position disengaging from the position applying a damping force to the drawer 200 in response to the bi-directional rotation of the shaft 410. That is, the rotation of the rotation shaft 410 in one direction can drive the damper 310 to slide to a position applying a damping force to the drawer 200, and the rotation of the rotation shaft 410 in the opposite direction can drive the damper 310 to slide to a position deviating from the position applying a damping force to the drawer 200.
Referring to fig. 2 and 3, the transmission unit 400 of the present embodiment further includes a unidirectional bearing 420 sleeved on the rotating shaft 410, and a bearing member 430 sleeved on the unidirectional bearing 420, and a driving member 210 is disposed on the drawer 200, where when the drawer 200 is pulled outwards, the driving member 210 can drive the bearing member 430 to drive the rotating shaft 410 to rotate through the unidirectional bearing 420, so that the damping member 310 slides to a position where the damping force is applied to the drawer 200.
Wherein the one-way bearing 420 is a bearing that can freely rotate in one direction and lock up in the other direction; through the one-way bearing 420, the drawer 200 can drive the rotation shaft 410 to rotate only when being pulled outwards; when the drawer 200 is pushed into the cabinet 100, the drawer 200 will not drive the rotation shaft 410 to rotate. It should be noted that the unidirectional bearing 420 may be an existing product, and the structure and the working principle thereof will not be described herein.
Based on the above structure, when the drawer 200 is pulled from the innermost side to the outer side, the rotation of the rotation shaft 410 can be driven to rotate, and the rotation of the rotation shaft 410 drives the damper 310 to be away from the drawer 200, so that the pull-out of the drawer 200 is not affected by the damping force of the damper 310.
In some embodiments, two damping members 310 are respectively screwed to two ends of the rotating shaft 410; and at least one coil spring is provided between the cabinet 100 and the rotation shaft 410, the coil spring applying an elastic force to the rotation shaft 410, the elastic force driving the rotation shaft 410 to rotate in a direction that slides the damping member 310 to apply damping force to the drawer 200.
In this embodiment, by screwing the two damping members 310 to the two ends of the rotating shaft 410, the two damping members 310 at the two ends can be respectively driven to slide in both directions when the rotating shaft 410 rotates in both directions. In this embodiment, by providing the above coil spring, when the drawer 200 is pulled outwards and drives the rotating shaft 410 to rotate, the coil spring can store energy, when the bearing member 430 is separated from the driving member 210, the rotating shaft 410 can reversely rotate under the driving of the coil spring, and drives the damping member 310 to slide in the direction capable of applying damping force to the drawer 200, when the drawer 200 is inserted into the cabinet 100 next time, the damping member 310 applies damping force to the drawer 200, so as to avoid the excessive speed of the drawer 200 in the process of pushing the drawer 100.
In the embodiment, the drawer 200 is pulled outwards to drive the rotating shaft 410 to rotate through the unidirectional bearing 420, so that the damping piece 310 slides away from the drawer 200, and meanwhile, the coil spring is used for storing energy; after the drawer 200 is pulled out to the outside so that the driving member 210 is separated from the bearing member 430, the coil spring drives the rotation shaft 410 to rotate reversely, so that the damping member 310 slides in the direction of applying damping force to the drawer 200, so that damping force is applied to the drawer 200 when the drawer 200 is inserted into the cabinet 100, and the rotation shaft 410 is not driven to rotate when the drawer 200 is pushed into the cabinet 100 due to the use of the unidirectional bearing 420.
In this embodiment, referring to fig. 2 to 5, an eccentric ejector rod 411 is respectively disposed on the end surfaces of two ends of the rotating shaft 410, an annular groove 301 concentric with the rotating shaft 410 is disposed on the damping member 310, and the ejector rod 411 extends into the annular groove 301 and abuts against the bottom surface of the annular groove 301; and at least one section of the bottom surface of the annular groove 301 is configured to gradually rise in the rotation direction of the rotation shaft 410 when the cabinet 100 is pulled outward, and a first elastic member 440 is provided between the damping member 310 and the cabinet 100, and the first elastic member 440 pushes the damping member 310 to slide to a position where the damping force is applied to the drawer 200.
Wherein, at least one section of the bottom surface of the annular groove 301 is configured to gradually rise in the rotation direction of the rotation shaft 410 when the cabinet 100 is pulled outward means that: at least one section of the bottom surface of the annular groove 301 gradually approaches the rotation shaft 410 in the rotation direction of the rotation shaft 410 when the drawer 200 is pulled outward. Thus, when the shaft 410 rotates and the top rod 411 slides within the section, the damper 310 will be pushed away from the shaft 410 and away from the drawer 200 to stop applying the damping force to the drawer 200.
Referring to fig. 6, the bottom surface of the annular groove 301 of the present embodiment includes a rising section 302 and a falling section 303 which are connected end to end in order; the lifting section 302 gradually increases along the rotation direction of the rotating shaft 410 when the cabinet 100 is pulled outwards, and the lowering section 303 gradually decreases along the rotation direction of the rotating shaft 410 when the cabinet 100 is pulled outwards.
Referring to fig. 2, the first elastic member 440 of the present embodiment is a spring abutting between the damper 310 and the cabinet 100, and the spring applies a pushing force to the damper 310, so that the damper 310 slides to a position where a damping force is applied to the drawer 200.
When the drawer 200 is pulled outwards, the ejector rod 411 slides in the lifting section 302 to push the damping piece 310 away from the drawer 200, and the damping force is stopped to be applied to the drawer 200; thereafter, when the drawer 200 is pulled outwards, the ejector rod 411 slides in the descending section 303, and the damping member 310 gradually approaches the drawer 200 under the pushing of the first elastic member 440, but does not contact with the drawer 200, and does not apply a damping force to the drawer 200 until the driving member 210 on the drawer 200 is separated from the bearing member 430, the first elastic member 440 continues to push the damping member 310, and the damping member 310 pushes the rotating shaft 410 to rotate until the ejector rod 411 slides to the lowest point of the descending section 303, which is also the lowest point of the lifting section 302.
In the above scheme that the hinge 410 is screwed with the damping member 310, when the drawer 200 is pulled outwards, resistance from the hinge 410 is received, which is derived from the coil spring on one hand and from friction between the hinge 410 and the damping member 310 on the other hand, and when the drawer 200 is pulled outwards, the resistance provided by the coil spring gradually increases before the driving member 210 on the drawer 200 is separated from the bearing member 430 on the hinge 410; that is, in the case where the hinge 410 is screwed to the damper 310, the resistance force applied to the drawer 200 when the drawer 200 is pulled outward is larger than that in the case of the present embodiment, and it should be noted that the resistance force is still smaller than the damping force applied to the drawer 200 by the damper 310.
Also, after the driving member 210 is separated from the bearing member 430, the rotation shaft 410 is reset without constraint by the coil spring, and abnormal noise may be generated from the reset of the rotation shaft 410. In the solution of this embodiment, when the drawer 200 is pulled outwards, after the ejector rod 411 slides from the lowest point to the highest point of the lifting section 302, at this time, the distance between the damping member 310 and the drawer 200 is the largest, and when the drawer 200 is pulled outwards, the distance between the damping member 310 and the drawer 200 is gradually reduced, i.e. the rotating shaft 410 is slowly reset under the constraint of the drawer 200, so that abnormal noise can be avoided.
Referring to fig. 2 and 4, the carrier 430 of the present embodiment is a first gear fixedly sleeved on the carrier 430; the driving member 210 of the present embodiment is a rack fixed on the drawer 200 and capable of being meshed with the first gear; the first gear can be rotated by the movement of the rack with the drawer 200.
In some embodiments, the bearing member 430 may also be a friction wheel fixedly sleeved on the bearing member 430, and the driving member 210 is a friction strip fixedly arranged on the drawer 200 and capable of abutting against the friction wheel; when the drawer 200 moves, the friction bar can drive the friction wheel to rotate by the friction force between the friction bar and the friction wheel, and the friction bar and the friction wheel drive the gear to rotate by the rack have the same principle, and the description is omitted herein.
In this embodiment, a speed limiting mechanism 500 is disposed on the cabinet 100; and speed limiting mechanism 500 includes fixed part and rotation portion, and it has a plurality of jack catch 530 to articulate on the rotation portion, and is equipped with drive portion 600 between rotation portion and the rack, and drawer 200 outside pulling can drive rotation portion rotation, and when the rotation speed of rotation portion exceeded the speed threshold value, each jack catch 530 can outwards open and with fixed part joint.
In summary, the damping unit 300 can prevent the drawer 200 from colliding with the cabinet 100 due to excessive speed at the end section when the drawer 200 is pushed into the cabinet 100; by providing the speed limiting mechanism 500, the drawer 200 can be prevented from being collided with the cabinet 100 due to the excessive speed of the drawer 200 when the drawer 200 is pulled outwards.
Specifically, by providing the fixing portion and the rotating portion, the rotation speed of the rotating portion is positively related to the speed of the drawer 200 pulling outwards, and when the rotation speed of the rotating portion is higher than a certain speed threshold, that is, the speed of the drawer 200 pulling outwards exceeds a certain speed threshold, the claw 530 can be opened to be engaged with the fixing portion, so as to limit the rotation of the rotating portion, that is, limit the pulling of the drawer 200 outwards.
In a specific structure, referring to fig. 8 and 9, the fixing portion of the embodiment is an outer ring 510 fixedly arranged on the cabinet body 100, a plurality of clamping grooves 501 are arranged on the inner wall of the outer ring 510, the rotating portion is an inner ring 520 coaxial with the outer ring 510, and the transmission portion 600 is a second gear coaxially fixedly connected with the inner ring 520 and meshed with the rack; each of the jaws 530 is spaced apart along the circumference of the inner ring 520, and one end of each of the jaws 530 is hinged to the inner ring 520, and a second elastic member 540 is provided between the middle of the jaws 530 and the inner ring 520, and the second elastic member 540 urges the free end of each of the jaws 530 to retract toward the center of the inner ring 520.
Based on the above structure, when the rotation speed of the inner ring 520 is greater than a certain value, the jaws 530 can be opened outwards due to the centrifugal force and engaged with the outer ring 510 to limit the rotation of the inner ring 520, i.e., to limit the sliding of the drawer 200.
In this embodiment, referring to fig. 8 and 9, the second elastic member 540 is a tension spring disposed between the inner rings 520 of the jaws 530, so as to apply a tensile force to the jaws 530 in a natural state, and prevent the jaws 530 from being accidentally opened at a low rotation speed of the inner rings 520.
The whole process of the drawer type switch cabinet of the embodiment is as follows:
when the drawer 200 is pulled outwards, the speed of the drawer 200 cannot be too high, otherwise, the claw 530 on the inner ring 520 is clamped with the outer ring 510 due to centrifugal force, so that the drawer 200 cannot be pulled, and the drawer 200 is prevented from being too high when being pulled outwards, and the drawer 200 is prevented from being collided with the cabinet body 100 strongly;
when the drawer 200 is pushed into the inner cabinet 100, the damping unit 300 applies a damping force to the drawer 200 at the end section of the movement of the drawer 200, so as to avoid the excessive speed of the drawer 200 when the drawer 200 is pushed into the inner cabinet, and avoid the violent collision of the drawer 200 and the cabinet 100.
